And that's the kind of villain who brings his own ruin.
He's just going out his way to piss off the MC when things would just have been fine if he let go here.
He doesn't have to interact with Tsuyoshi any further than this, but he's going to antagonize the MC because he can't forget being frightened by a young commoner.
On a different platform, I commented how pride is like a drug.
With just the right amount, it's medicine that helps you. It brings self-confidence, it drives you forward despite adversity.
With an excess amount, it acts as a poison that ruins you. It brings arrogance, it makes you repeat mistakes until your downfall.
This old man is soon going to choke on his "godly" pride.
